Candace drives a total of 48 miles each day to get to work and back home. She works 5 days a week. Her car gets 21 miles per gallon of gas. About how many gallons does she need to drive to work and back home each week?
Answer:
11.43 gallons used exactly per week asuming not changes in schedule or any other reasons to drive and that a one way trip is 24 miles.
Step-by-step explanation:
48 as total for two trips
five of these need to be done, so 240 miles a week assuming no other reason to drive
240 / 21 = 10 with remainder 30
so 11 and remainder 9
9/21 = nearly .43 gallons, which means as a minimum she shouldn't go below 11.5 and better yet 12 gallons.
Candace drives 240 miles each week (48 miles per day * 5 days). Given her car's fuel efficiency is 21 miles per gallon, she would therefore need approximately 11.43 gallons of gas (240 miles / 21 miles per gallon) for her weekly commute.
Explanation:To answer the question of how many gallons of gas Candace needs to get to work and back home each week, you need to first know how many miles she is driving in total for that week.
First, let's find the total miles she drives weekly. We know she drives 48 miles each day to work and back home and she works 5 days a week. So, miles per week = 48 miles per day * 5 days per week = 240 miles per week.
Next, we know her car gets 21 miles per gallon of gas. To find the gallons required, we divide the weekly miles by the miles per gallon. So, Gallons used per week = 240 miles per week / 21 miles per gallon ≈ 11.43 gallons per week.
So, she needs approximately 11.43 gallons of gas to drive to work and back home each week.

A study has indicated that the sample size necessary to estimate the average electricity use by residential customers of a large western utility company is 900 customers. Assuming that the margin of error associated with the estimate will be ±30 watts and the confidence level is stated to be 90 percent, what was the value for the population standard deviation?
Answer:
[tex]\sigma=547.1125[/tex]
Step-by-step explanation:
-The margin of error is calculated using the formula:
[tex]ME=z_{\alpha/2}\times \frac{\sigma}{\sqrt{n}}\\\\[/tex]
-We substitute the values, n=900 and ME=30 in the formula to solve for standard deviation:
[tex]ME=z_{\alpha/2}\times \frac{\sigma}{\sqrt{n}}\\\\\\30=1.645\times\frac{\sigma}{\sqrt{900}}\\\\\sigma=\frac{30^2}{1.645}\\\\=547.1125[/tex]

7. It takes ounces of honey to make one apple pie. Betty baked 4 apple
pies. She also baked 4 pecan pies. Each pecan pie takes 4.4 ounces of
honey. How much honey did Betty use to bake the apple and pecan
pies?
ir
Answer:
17.6 ounces to make the pecan pies. I dont know how much honey she used to make the apple pie so if you could pls say I could edit the answer :)
Step-by-step explanation:
Betty used a total amount of honey equal to 4 times the ounces of honey needed for one apple pie plus 17.6 ounces of honey for the pecan pies. The exact total amount of honey used cannot be determined without knowing the amount of honey (x) used in an apple pie.
Explanation:The question is asking how much honey Betty used to bake apple and pecan pies. First we need to determine the amount of honey required per pie and then add the total amounts for each type of pie. Let's say it takes x ounces of honey to make one apple pie. Since Betty baked 4 apple pies, she would use 4x ounces of honey for the apple pies. For the pecan pies, each requires 4.4 ounces of honey, so for 4 pecan pies she would use 4 × 4.4 ounces which equals 17.6 ounces of honey.
To find the total honey used, add the honey used for apple pies and pecan pies: 4x + 17.6 ounces. Without the specific amount of honey for the apple pies (x), we cannot calculate the exact total amount of honey used.
The population of cirque city was 43,129 in 1999 and was 56,780 in 2010. If the population was growing exponentially what was the growth rate
Answer:
r=2.5%
Step-by-step explanation:
An exponential growth distribution is generally expressed as:
[tex]P_t=P_oe^{rt}[/tex]
where:
[tex]P_t[/tex] is population at time t[tex]P_o[/tex] is the initial population[tex]r[/tex] is the rate of growth and t=time#Substitute the given values to solve for r:
[tex]P_{2010}=P_{1999}e^{(2010-1999)r}\\\\56780=43129e^{11r}\\\\1.31652=e^{11r}\\\\\\r=\frac{In \ 1.31652}{11}\\\\=0.024999\approx 2.5\%[/tex]
Hence, the rate of growth is approximately 2.5%
The population of Cirque City was growing exponentially at a rate of approximately 2.5% per year from 1999 to 2010.
To determine the exponential growth rate of the population in Cirque City, we will use the formula for exponential growth:
P(t) = P0 × [tex]e^{rt}[/tex]
Here, P(t) is the population at time t, P0 is the initial population, r is the growth rate, and t is the time period. Given data: P0 = 43,129 (population in 1999), P(t) = 56,780 (population in 2010), and t = 11 years. Our goal is to find r.
Start with the formula and substitute the known values:
P(t) = 43,129 × [tex]e^{11r}[/tex] = 56,780
Isolate the exponential term:
[tex]e^{11r}[/tex] = 56,780 / 43,129
[tex]e^{11r}[/tex] ≈ 1.315
Take the natural logarithm (ln) of both sides to solve for r:
ln( [tex]e^{11r}[/tex]) = ln(1.315)
11r = ln(1.315)
r ≈ ln(1.315) / 11
Calculate the value:
r ≈ 0.025
Convert to a percentage:
r ≈ 2.5%
Therefore, the population of Cirque City was growing at an exponential rate of approximately 2.5% per year.
here is a right cone. what is the one shape of cross section we could create by slicing the cone parallel to its base
When a right cone is sliced parallel to its base, the resulting cross section is always a circle.
Explanation:If a cone is sliced parallel to its base, the shape that results is a circle. This is an aspect of conic sections, which are the curved shapes created when a plane intersects a cone. Other than circles, other possible shapes that we can obtain from slicing a cone include ellipses, parabolas, and hyperbolas, depending on the angles and location of the slice made. However, when the cut is parallel to the base, a circle is always formed. This is due to the consistent radius from the cone's axis to its slant height along the same parallel plane.

Find the accumulated value of an investment of 15,000 for 4 years at an interest of 4% if the money is a. Compound semiannually; b. Compounded quarterly; c. Compounded monthly; d. Compounded continuously.
Answer:
Compounded Semiannually: $17,574.89
Compounded Quarterly: $17,588.68
Compounded Monthly: $17,597.98
Compounded Continuously: $17,602.66
Step-by-step explanation:
Lets use the compound interest formula provided to solve this:
[tex]A=P(1+\frac{r}{n} )^{nt}[/tex]
P = initial balance
r = interest rate (decimal)
n = number of times compounded annually
t = time
First, change 4% into a decimal:
4% -> [tex]\frac{4}{100}[/tex] -> 0.04
Now, plug in the values to the equation:
Compounded Semiannually:
[tex]A=15,000(1+\frac{0.04}{2})^{2(4)}[/tex]
[tex]A=17,574.89[/tex]
Compounded Quarterly:
[tex]A=15,000(1+\frac{0.04}{4})^{4(4)}[/tex]
[tex]A=17,588.68[/tex]
Compounded Monthly:
[tex]A=15,000(1+\frac{0.04}{12})^{12(4)}[/tex]
[tex]A=17,597.98[/tex]
To find the value if compounded continuously, use the following formula:
[tex]A = Pe^{rt}[/tex]
[tex]A=15,000e^{0.04(4)}[/tex]
[tex]A=17,602.66[/tex]
The accumulated value of an investment is calculated differently depending on the compounding period - semiannually, quarterly, monthly or continuously. This involves the compound interest formula and understanding of how interest rates work.
Explanation:The subject of this question is about calculating the accumulated value of an investment at a given interest rate with various compounding periods i.e., semiannually, quarterly, monthly, and continuously. We first need to understand that compound interest is calculated on the principal plus the accumulated interest.
To calculate the future value of the investment, we use the compound interest formula: P*(1+r/n)^(nt), where P is the principal (or initial investment), r is the annual interest rate (in decimal form), n is the number of compounding periods per year, and t is the time in years.
Semiannually: P*(1+r/2)^(2*4)Quarterly: P*(1+r/4)^(4*4)Monthly: P*(1+r/12)^(12*4)Continuously: P*e^(rt), where e is Euler's number, approximately equal to 2.71828.Learn more about Compound Interest here:https://brainly.com/question/34614903

Rewrite the function to determine whether it represents exponential growth or exponential decay. Identify the percent rate of change. Round numbers to the nearest hundredth, if necessary. y=(1.06)8t In the form y=a(1+r)t, the function is y≈ . To the nearest percent, the rate of change is a %.
Answer:
y ≈1*(1+0.59)^t. The rate of change is = 59%
Step-by-step explanation:
We have t mulitplied by 8 in the expression of y. We can write that power with a power of powers, using the property
[tex]a^{bc} = (a^b)^c = (a^c)^b[/tex]
Therefore,
[tex]a^{8t} = (a^8)^t[/tex]
If we replace a with 1.06, we obtain
[tex] y = 1.06^{8t} = (1.06^8)^t \approx 1.59^t = 1*(1+0.59)^t[/tex]
Thus, y ≈1*(1+0.59)^t. The rate of change is ln(1.59) * 1.59^t. After 1 unit of time t, the rate of change is 0.59*100 = 59%
The given function represents exponential growth with a rate of change of 6%. The function already fits the form y = a(1 + r)^t with a = 1 and r = 0.06.
Explanation:To rewrite the function y = (1.06)^8t in the form y = a(1 + r)^t, we can identify a as the initial amount and r as the rate of change. In this case, the initial amount a is implied to be 1 (since it is not explicitly multiplied by the base), and the base 1.06 represents the growth factor. Seeing as the base is greater than 1, this function represents exponential growth.
The percent rate of change can be found by subtracting 1 from the base and then converting it to a percentage. Therefore, the rate r is 1.06 - 1, which equals 0.06 or 6% when expressed as a percentage. Thus, the function in the requested form is y = (1 + 0.06)^8t, or simplifying the exponent, y = (1.06)^8t.
To the nearest percent, the rate of change is 6%.

What is the height of the stone at the time it is thrown?
Answer:
The height of the stone at the time it is thrown is 15.
Step-by-step explanation:
You have a quadratic function of the form h (x) = ax² + bx + c. In this case it is h (x) = -5x²+10x+15, where a =-5, b =10, c =15, x is the time and h (x) is the height of the stone after being thrown.
The moment the stone is thrown is instant zero. So if x = 0, h (0) is calculated:
h(0)= -5*0² +10*0 +15
h(0)= 0 + 0 + 15
h(0)= 15
The height of the stone at the time it is thrown is 15.

Answer:
They predict 1350 renters will buy liability insurance.
The answer is 1350 renters.
Step-by-step explanation:
Given:
A car rental company at the local airport estimates they sell liability insurance to 45% of their customers.
If they rent 3,000 cars next month.
Now, to find the renters they predict will buy liability insurance.
So, the rate of the car rental company which estimates of selling liability insurance to their customers is 45%.
And, the cars they rent next month = 3,000.
Now, to get the renters they predict of buying liability insurance by getting the rate of the cars they rent next month:
[tex]45\%\ of\ 3,000\\\\=\frac{45}{100}\times 3,000\\\\=0.45\times 3,000\\\\=1350.[/tex]

Thomas rays parents begin saving to buy their son a car for his 16th birthday. they save $800 the first year and each year they save 5% more than the previous year. How much money will they have saved for his 16th birthday.
Answer:
money they will have saved for his 16th birthday = $18,926
Step-by-step explanation:
This is a geometric series problem.
The sum of a geometric series is given by the formula;
Sn = a1•(rⁿ - 1)/(r - 1)
Where;
a1 is the first term
n is the number of terms
r is the constant ratio
Now, in this question, they started saving since he was born till his 16th birthday. That's 16 years. Thus number of terms; n = 16
Also, the first money saved was $800, thus the first term; a1 = 800
They save 5% more each year than the previous year. That's an increase of 1.05 each year. Thus, the common ratio; r = 1.05
The amount of money they will have by his 16th birthday will be;
S_16 = 800•(1.05^(16) - 1)/(1.05 - 1)
S_16 = 800(1.18287458838/0.05)
S_16 = $18,926
S16 = $800·(1.05^16 -1)/(1.05 -1)

Animal Clinic and the mean cost to treat cats at A New Leash on Life Animal
Clinic is about 10 times the MAD This is a large difference.
Step-by-step explanation:
I GOT THIS RIGHT! THIS IS THE ANSWER
The differences in mean costs to treat dogs and cats compared to the MAD at A New Leash on Life Animal Clinic suggest different levels of variability in the data. A 19 times difference labeled as 'moderate' implies high variability, while if labeled as 'large', the implication is that the variability is lower.
Explanation:The question relates to the comparison of the mean costs to treat dogs and cats at A New Leash on Life Animal Clinic, using the Mean Absolute Deviation (MAD) as a measure of variability. When we say that the difference between the mean cost to treat dogs and cats is about 19 times the MAD, and that this is a moderate difference, it suggests that the variability within each of the distributions is quite high, making a 19-fold difference in means seem less extreme. Conversely, the same difference being described as a large difference implies that the variability (MAD) is comparatively lower, hence a difference of the same scale appears more substantial relative to the spread of the data. This provides insight into the differences in treatment costs and the consistency of those costs within each group of animals.
